cover joint

36,37 can be constructed so that the screening canopy of desired configuration and size to be provided in a different manner by those skilled in the art.

(0020) ridge bar 38 extends between two cover joints 36,37.Ridge bar 38 provides two functions.At first, the top of ridge bar 38 supports fabrics ceilings 24.Secondly, the ridge bar is two

cover joints

36,37 separately, can cover more ground and needn't improve height that hides canopy 20 or the angle that reduces fabric ceiling 24 thereby hide canopy 20, and the latter understands the edge that causes water to collect in fabric ceiling 24 undesirablely.

(0021) shown that in Fig. 2 cover saves 36 details.As mentioned above, this cover joint 36 is identical with cover joint 37.Therefore, in order to be easy to describe, in the cover joint is only described, i.e. the structure of cover joint 36 here.

(0022) cover joint 36 is a triangle, opening 40,42, and 44 are located at each turning.Opening 40-44 is the elongated hole that extends towards the center of cover joint 36.Opening 44 comprises circular cross section, and opening 40,42nd is oblong, and has cross section, and this cross section has straight flange 43 (Fig. 3) and circular top and bottom 45.

(0023) each among the opening 40-44 comprises top that extends through cover joint 36 and the slit 46 that enters opening.Opening 40,42 is configured to hold the

end

48,50 of upright pole 26,28.The cross section of these

ends

48,50 is narrower slightly than the remainder of

pole

26,28, is Long Circle, and comprises straight flange 49 and circular top and bottom 51, and this can see in Fig. 2 and 3.Preferably

end

48,50 is sized to the straight flange 43 (Fig. 3) and circular top and the bottom 45 that make straight flange 49 and circular top and bottom 51 closely cooperate opening 40,42.

(0024)

clip

52,54 is disposed in the inside of each

end

48,50 of upright pole 26,28.The part of each

clip

52,54 is stretched out slit 55 from

upright pole

26 or 28 top separately.As known in the art,

clip

52,54 is designed to be extruded inward when terminal separately 48,50 of

pole

26,28 extends in opening 40 or 42.

Clip

52,54 pops up the respective slots 46 of opening 40 or 42 then.Similarly the clip (not shown) can be located at the end of ridge bar 38.

(0025)

terminal

48,50 straight flange 49 and circular top and bottom 51 closely cooperate straight flange 43 and the circular top and the bottom 45 of opening 40,42, thereby prevent top 35 rotation in cover joint 36 of upright pole 26,28.This is characterized as screening canopy 20 improved stability is provided, and this is to have prevented that bottom 34 is mobile on the direction of arrow K shown in Fig. 1 and M because prevent the rotation on the top 35 of upright pole 26,28.Reduce this torsional effect and increased the stability that hides canopy 20, make the screening canopy more stable under the high wind condition.

(0026) although the structure of

end

48,50 and opening 40,42 is suitable for preventing to reverse well, also can use other structure.Pole can not carried out this function with respect to any structure of cover joint rotation when generally speaking, allowing

upright pole

26,28 to be connected to the cover joint.An example is the oblong shape that is used for opening 40,42 and terminal 48,50.Another example comprises at least one outstanding and corresponding abutment surface in each opening.Yet the particular configuration of Xian Shiing suits in the drawings, and reason is that the benefit that described structure is enjoyed is the intensity with tubular struts, and has and prevent the structure that reverses.

(0027) in the embodiment shown in Fig. 1-3, be used to admit the opening 44 of ridge bar 38 not have the irregular cross section of the opening of being similar to 40,42.This is because do not influence the stability of screening canopy 20 reversing of ridge bar 38.Yet if desired, ridge bar opening 44 also can comprise end and the opening that is configured to prevent 38 rotations of ridge bar.

(0028) in order to help upright

pole

26,28 aim at and are assembled into cover joint 36, the such mark of letter shown in Fig. 2 " A " and " B " can be located near the edge separately of opening 40 or 42, and near the end separately 48 or 50 of upright pole 26,28.Like this, the user can assemble

upright pole

26,28 apace, and the bottom 34 of

upright pole

26,28 is directed into correctly in upper/lower positions, and can not cause the user to attempt in the

upright pole

26,28 any one is connected to opening 44.

(0029) as mentioned above, although each in the

upright pole

26,28,30 and 32 is shown as extending to from the top that hides canopy 20 the continuous pole on ground, described pole can partly be made by a plurality of poles.These pole parts can be connected by inner shock cord in mode as known in the art.In addition, one or more intermediate structures can be located between the different piece of upright pole, for example between the upper and lower portion 35,34.Yet,, between the position on the pole under the elbow 33 of the junction of separately upright pole and cover joint 36 and upright pole, should not rotate for fear of bottom 34 rotation of upright pole 26-32.Therefore, if sections is located between this position and the cover joint 36, after these sections should be constructed such that proper installation, they can relative to each other not rotate.

(0030) in Fig. 4, shown another embodiment that hides canopy 56.Hide canopy 56 and comprise the fulcrum bar component 58 with four upright poles 60,62,64,66, described four upright poles are covered by fabric ceiling 68 at the top.This screening canopy 56 is similar to and hides canopy 20, but does not comprise ridge bar 38 and only have a cover joint 70.In addition, cover joint 70 has four spokes that are used to connect four upright pole 60-66.

(0031) because each opening in the cover joint 70 is connected to upright pole 60-66, preferably each upright pole will be connected to the opening separately of cover joint 70 and not allow rotation.For example, each opening can comprise the Long Circle cross section shown in the opening 40 and 42 that is similar in Fig. 2 and 3.Thereby each that forms upright pole 60-66 and cover joint 70 is connected, makes upright pole 60-66 separately can not rotate with respect to cover joint 70.

(0032) also can predict other embodiment that hides canopy.For example, screening canopy in five limits can comprise the five spokes cover joint that is connected to five upright poles.

(0033) upright pole does not suit with detachably, being rotatably connected of cover joint, and reason is that it has avoided upright pole with respect to the rotation of cover joint and improved the stability of screening canopy.Disclosed structure increases cost hardly and reduces the intensity of upright pole hardly among the realization figure.

(0034) advantage of disclosed upright pole is that they provide unique support for fabric ceiling 24 in the drawings.Therefore, hide canopy and can be made lighter, and be easy to assembling and storage.The fact that top 35 and elbow 33 can not rotate provides the structural support of downward extension for the bottom of the upright pole that can not rotate.Thereby, do not need to be used for the additional support of the structural support of extension, for example pole or other structure downwards.

(0035) if desired, can between cover joint and upright pole, carry out different connections.For example, the cover joint can comprise outstanding, and the end of upright pole is positioned on described the giving prominence to.For this reason, cover joint can be any structure that is used to connect the top 35 of two upright poles.

(0036) according to another embodiment of the present invention, if desired, one in the upright pole (for example upright pole 60-66) with respect to cover joint (for example the cover joint 70) rotation, and described specific upright pole can form one or for good and all be connected to cover joint 70 with cover joint 70.Yet other upright pole and ridge bar 38 (if applicable) are preferred detachable, thereby fulcrum bar component 22 or 58 can be disassembled into minor structure to be used for storage.

(0037) other modification is in spirit of the present invention.Therefore, although the present invention obtains various improvement and alternative constructions easily, its certain embodiment that exemplifies illustrates in the drawings and specifically is described in the above.Yet, should be appreciated that and not want to limit the present invention to disclosed one or more particular form, but opposite, the present invention will be contained all improvement that fall into the spirit and scope of the present invention, alternative constructions, and equivalent, the spirit and scope of the present invention are limited by appended claim.
